Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

Journal of Zoology, EarlyView.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Influence of vapour pressure deficit and CO2 on the thermal sensitivity of stomatal function in tropical trees

New Phytologist, EarlyView.
Examining the potential thermal sensitivity of the model parameter g1 when accounting for the additive nature of underlying components including CO2 compensation point (Г*) and the marginal water cost of plant carbon gain (λ), when assuming λ is dependent upon changes in the viscosity (inverse of fluidity) of water (η, Pa·s) and the solubility of CO2 ...

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

New Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Fine‐root trait variation in temperate trees follows arc‐shape pattern along deep soil profiles

New Phytologist, EarlyView.
Root trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.

Key sources of uncertainty in process‐based modeling of live fuel moisture content

New Phytologist, EarlyView.
Location of the selected live fuel moisture content (LFMC) sampling sites. Summary Process‐based models that mechanistically represent water‐carbon balances in the atmosphere‐soil–plant continuum are an attractive tool for monitoring live fuel moisture content (LFMC) dynamics, a key variable when assessing fire danger.
